It's so incredibly difficult to say who the greatest player of all time is, because the four are such different players. Wilt Chamberlain, Magic Johnson, Michael Jordan, Lebron James. All four are such different players.
Pure assassin - Jordan. Numbers - Chamberlain. Physical freak - James. Completely different for his time - Magic.
Comparing Lebron to Jordan is ridiculous. They are completely different players. Hell, you could add Bill Russell to this conversation.
Saying James is a failure if he loses tonight is ridiculous. His supporting cast is nowhere near Jordan's. Wade hurt, nowhere near his prime. Bosh is not Rodman in that role (3rd guy) at all.
